For the walks the main point was based on the masonry walks this help us to describe the building’s composition more easy. In the walk we learn about the the different type of mansard such as: granite, marble, limestone, stone and brick. after this walk help us to learn more about masonry and we understood that the stone can be found by large pits when all the material are harvested. I think this walk was so fun because make us be able to talk about the mansard with a nice knowledge.
